I was commuting to work this morning and was following a bus, suddenly I saw a huge crack, no time to steering around so just run over it. Then I felt my bike not steering properly. Pulled over and had a check I found the front tyre was complete flat. That must be from the impact because a puncture should take longer to flat a tyre. The inner tube may have exploded (haven't checked). Never MTB before so wondering is front of a bicycle takes more impact than rear? Is that why MTB has longer travel in the front?
Thanks everyone for the inputs. I have checked the front tube, there is 2-3 mm slit, so definitely from an explosion. That means the front tyre hit the crack, then deformed too much at the impact. Looking at vehicles in crashes (front ), they all have badly deformed front, rear is relatively intact. If front doesn't deform, then the force will go through all vehicle and cause even more damage to the driver. I think it's similar here.
